Subject: kv/memdb: fix uninitialized return of MemDB::_init().
X-Git-Tag: v16.1.0~430^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=72454ef712b20109cdf5966ae6945d6aa1b4d68c;p=ceph.git

kv/memdb: fix uninitialized return of MemDB::_init().

Without this fix GCC complains:

```
src/kv/MemDB.cc:179:10: warning: ‘r’ may be used uninitialized in this function [-Wmaybe-uninitialized]
  179 |   return r;
```
